    "Try starting with the adjusters 1.5 turns out to start with and fine tune from there. If the engine spits back and has a misfire,check for water in the fuel system. This is happens often with the old pressure tank system."

    "Water in the fuel system can happen in any kind of design.

    Don't try to adjust both at once. Start with throttle on start, the high speed about 1 turn out and go counterclockwise until it fires. Get it running smoothly on the high speed, then go down to the slow speed."

    Default There is no water in the fuel.

    There is no water in the fuel..This engine has been sitting for 15-20 years...I replaced the points and rebuilt the carb and put in new plugs...Most engins require about a turn and a half...I am not sure about this one though...

    Default "(Carburetor Adjustments -

    "(Carburetor Adjustments - Two Adjustable N/Vs)
    (J. Reeves)

    Initial settings are: Bottom high speed = seat gently, then open 1 turn out. Top slow speed = seat gently, then open 1-1/2 turns.

    Setting the high and low needle valves properly:

    NOTE: For engines that DO NOT have a shift selection, obviously there is no NEUTRAL position. Simply lower the rpms to the lowest setting to obtain the low speed needle va /lve adjustment.

    (High Speed) Start engine (it will run pretty rough), shift into forward gear, take up to full throttle. In segments of 1/8 turn, wating for the engine to respond between turns, start turning in the bottom high speed needle valve. You'll reach a point whereas the engine will either start to die out or spit back (sounds like a mild backfire). At that point, back out the needle valve 1/4 turn. Within that 1/4 turn, you'll find the smoothest setting.

    (Low Speed) Slow the engine down to where it just stays running. Shift into neutral. Again in segments of 1/8 turns, start to turn the top needle valve in. Wait a few seconds for the engine to respond. As you turn the valve in, the rpms will increase. Lower the rpms again to where the engine will just stay running. Eventually you'll hit the point where the engine wants to die out or it will spit back. Again, at that point, back out the valve 1/4 turn. Within that 1/4 turn, you'll find the smoothest slow speed setting.

    When you have finished the above adjustments, you will have no reason to move them again unless the carburetor fouls/gums up from sitting, in which case you would be required to remove, clean, and rebuild the carburetor anyway."
